Question

The detergent used in hair conditioner is

• A. $C{H}_3\left(C{H}_2{)}_{15}{N}^{+}\right(C{H}_3{)}_{3}C{l}^{-}$
• B. $C{H}_3(C{H}_2{)}_{15}N{H}_2$
• C. $C{H}_3(C{H}_2{)}_{15}NHC{H}_3$
• D. $C{H}_3\left(C{H}_2{)}_{15}N\right(C{H}_3{)}_2$

Answer 1

The correct option is A $C{H}_3\left(C{H}_2{)}_{15}{N}^{+}\right(C{H}_3{)}_{3}C{l}^{-}$

Cationic part possesses a long hydrocarbon chain and a positive charge on nitrogen atom. Hence, these are called cationic detergents.Cetyltrimethylammonium chloride $C{H}_3\left(C{H}_2{)}_{15}{N}^{+}\right(C{H}_3{)}_{3}C{l}^{-}$ is a popular cationic detergent and is used in hair conditioners.
